It's being called the most polluted spot on the planet. While Russia's Lake Karachay might look pretty in a painting that's as close as you ever want to get to it.
In 1990, the US organization "Natural Resources Defense Council" got their hands on a formerly secret soviet publication that revealed quote "astronomically" high radioactive pollution.
The lake sits in western Russia near the border of Kazakhstan. Nearby is Mayak, formerly known as Chelyabinsk one of the country's largest nuclear production sites.

The reports say for years Chelyabinsk dumped about 120 million curies of radioactive waste to give you an idea of how much that is -- it's two and a half times the amount of radiation released in Chernobyl.
Add on top of that the Kyshtym nuclear disaster in 1957 said to be on of the world's worst ever, a drought and strong winds blowing radioactive waste around.
The NRDC said that sitting on the lake's shores for just an hour would be long enough to kill you!
